While `clippy` now allows `TBD` to be used in `since` parameter of
`deprecated` attribute it is only available in the newest, nightly,
version. Switch `clippy` version to nightly to enable the `TBD` value.
Currently `bitcoin` cannot be built with no features enabled, it must
have either "no-std" or "std" enabled. This is an artifact from when
we depended on `core2` for "no-std", now that we have our own `io` crate
and we unconditionally depend on it we can remove the "no-std" feature.

Pull request description:
The format bot defaults to using the person who triggered the workflow. We can use the `author` option to configure a dummy bot author.

Rust version 1.56.0 introduced edition 2021. Shortly afterwards, on
October 21 2021 Rust version 1.56.1 was released.
Debian stable is currently shipping `rustc 1.63.0`.
Our stated MSRV policy is: In Debian stable and at least 2 years old.
Therefore our MSRV policy is met by Rust version 1.56.1 and we can strat
to bump our MSRV org wide.
Start by bumping the `rust-bitcoin` and `hashes` MSRV to Rust 1.56.1,
includes:
- Update docs.
- Update CI and remove pinning.
- Update the build files and remove now stale cfg attributes rust_v_1_x
for values less than the new MSRV.
- Use new `IntoIterator` for arrays so we no longer need to allocate a
vector to iterate.

c34c709681 CI: add an automated github releases on new tags (Einherjar)
Pull request description:
Creates a `gh-release.yml` that runs on every new tag using the [`ncipollo/release-action`](https://github.com/ncipollo/release-action), which is one of the recommended actions after [GitHub's official `actions/create-release`](https://github.com/actions/create-release) was archived.
The idea is to just have a release with the source code, no binary (although if wanted I can add that as well).
A little bit of context: tcharding told me yesterday at TABConf that he copied manually all commits titles to the release notes somewhere (I think in crates.io?).
This is an easy way to do it, just copy from the GitHub release.
Finally, it is also positive to generate Releases from Tags since this increases the exposure of the repo (GitHub is highly social) while also signaling maturity.
Here's an [example](https://github.com/oven-sh/bun/releases/tag/bun-v0.8.1) that I've found in a non-related repo that has the same `generateReleaseNotes: true` as this PR proposes

daa70ea931 Bump actions/cache from 2 to 3 (dependabot[bot])
Pull request description:
Bumps [actions/cache](https://github.com/actions/cache) from 2 to 3.
<details>
<summary>Release notes</summary>
<p><em>Sourced from <a href="https://github.com/actions/cache/releases">actions/cache's releases</a>.</em></p>
<blockquote>
<h2>v3.0.0</h2>
<ul>
<li>
<p>This change adds a minimum runner version(node12 -> node16), which can break users using an out-of-date/fork of the runner. This would be most commonly affecting users on GHES 3.3 or before, as those runners do not support node16 actions and they can use actions from github.com via <a href="https://docs.github.com/en/enterprise-server@3.0/admin/github-actions/managing-access-to-actions-from-githubcom/enabling-automatic-access-to-githubcom-actions-using-github-connect">github connect</a> or manually copying the repo to their GHES instance.</p>
</li>
<li>
<p>Few dependencies and cache action usage examples have also been updated.</p>
</li>
</ul>
<h2>Updating actions/core to version 1.10.0</h2>
<p>The ::save-state and ::set-output are deprecated. The newer version of actions/core >1.10.0 uses the new syntax for save and set output. After this change, customers using actions/cache@v2 won't see deprecation warning message.</p>
<h2>v2.1.7</h2>
<p>Support 10GB cache upload using the latest version <code>1.0.8</code> of <a href="https://www.npmjs.com/package/@actions/cache"><code>@actions/cache</code> </a></p>
<h2>v2.1.6</h2>
<ul>
<li>Catch unhandled "bad file descriptor" errors that sometimes occurs when the cache server returns non-successful response (<a href="https://redirect.github.com/actions/cache/pull/596">actions/cache#596</a>)</li>
</ul>
<h2>v2.1.5</h2>
<ul>
<li>Fix permissions error seen when extracting caches with GNU tar that were previously created using BSD tar (<a href="https://redirect.github.com/actions/cache/issues/527">actions/cache#527</a>)</li>
</ul>
<h2>v2.1.4</h2>
<ul>
<li>Make caching more verbose <a href="https://redirect.github.com/actions/toolkit/pull/650">#650</a></li>
<li>Use GNU tar on macOS if available <a href="https://redirect.github.com/actions/toolkit/pull/701">#701</a></li>
</ul>
<h2>v2.1.3</h2>
<ul>
<li>Upgrades <code>@actions/core</code> to v1.2.6 for <a href="https://github.com/advisories/GHSA-mfwh-5m23-j46w">CVE-2020-15228</a>. This action was not using the affected methods.</li>
<li>Fix error handling in <code>uploadChunk</code> where 400-level errors were not being detected and handled correctly</li>
</ul>
<h2>v2.1.2</h2>
<ul>
<li>Adds input to limit the chunk upload size, useful for self-hosted runners with slower upload speeds</li>
<li>No-op when executing on GHES</li>
</ul>
<h2>v2.1.1</h2>
<ul>
<li>Update <code>@actions/cache</code> package to <code>v1.0.2</code> which allows cache action to use posix format when taring files.</li>
</ul>
<h2>v2.1.0</h2>
<ul>
<li>Replaces the <code>http-client</code> with the Azure Storage SDK for NodeJS when downloading cache content from Azure. This should help improve download performance and reliability as the SDK downloads files in 4 MB chunks, which can be parallelized and retried independently</li>
<li>Display download progress and speed</li>
</ul>

This will make the rust-toolchain to always run in the `stable` branch with the toolchain version being handled in the action.
It will appease dependabot and we can change at any time the `toolchain` action input.
Currently we run the release jobs for all PRs, this leads to red CI runs
any time we have unreleased changes in one crate used by another i.e.,
basically days after a release comes out.
Add a `release.sh` script that has more smarts to try and figure out if
the patch series currently ontop of tip of mater contains changes that
imply its a release PR. To do so we check for changes to the version
field in the manifest of each crate.

Enable formatting in CI by doing:
- Add a section to the `test.sh` scripts to run the formatter (guarded by
the env variable `DO_FMT`) for all crates (bitcoin, hashes, internals).
- Add `DO_FMT` to the nightly `Tests` CI job.

Currently the docs build commands in `hashes` and `bitcoin` differ, they should be the same.

Done after seeing: https://github.com/rust-bitcoin/rust-bitcoin/pull/1504 and CI should fail on this PR until 1504 is in.

When we merged `hashes` into `rust-bitcoin` we ran the test script a
couple of times using `./hashes/contrib/test.sh` this causes the `cargo`
commands in the CI script to be run from the crate root which is not
what we want.
This showed up recently because `cargo test` was getting run in
`bitcoin` after building with address/memory sanitazation configured
into the build.
While we are at it run `cargo clean` after the last sanitizer build just
to future proof the CI script in case we later accidentally re-use the same
build with plain old `cargo` (without `-Zbuild-std etc.`).
Currently the docs build commands in `hashes` and `bitcoin` differ, they
should be the same.
Add a command `cargo doc` to improve coverage e.g., recently we botched
the feature guarding but since CI only runs `cargo rustdoc` with custom
compiler conditional set we didn't catch it.
Run docs in CI using nightly and stable toolchains as required.

Running kani takes ages, instead of running it on every pull request we can just run it daily.

4201612837 Use dtonlnay instead of actions-rs (Tobin C. Harding)
Pull request description:
Done on top of #1508
Currently we use the `actions-rs` GitHub action to run our tests. It seems the project is now unmaintained [0].
Well known Rust developer dtonlnay maintains a GitHub action that can be used instead.
Replace all uses of `actions-rs/toolchain` with `dtonlnay/rust-toolchain`. Note that with the new action there is no way to configure the toolchain, instead a different `uses` statement is required - this means we have to split our jobs up by toolchain. This is arguably cleaner anyways.
Note that with this patch applied the "no-std" tests are now _not_ run for MSRV since we explicitly support "no-std" only for the 1.47 and above toolchains - strange that this was working?

This patches `bitcoin_hashes` to use the version in the repository and
fixes the code after removal of `Deref`.
This also turns off `AS_DEPENDENCY` check with the intention to refactor
it later.
We would like to bring the `bitcoin_hashes` crate into the
`rust-bitcoin` repository.
Import `bitcoin_hashes` into `rust-bitocin/hashes`, doing so looses all
the commit history from the original crate but if we archive the
original repository then the history will be preserved. We maintain the
same version number obviously and in the changelog we note the change of
repository.
Commit hash that was tip of `bitcoin_hashes` at time of import:
commit 54c16249e06cc6b7870c7fc07d90f489d82647c7
Includes making `embedded` and `fuzzing` per-crate i.e., move them into
`bitcoin` as hashes includes these also.
NOTE: Does _not_ enable fuzzing for `hashes` in CI.
Notes on CI:
Attempts to merge in the github actions from the hashes crate however reduces
coverage by not running hashes tests for beta toolchain. Some additional
work could be done to improve the CI to increase efficiency without
reducing coverage. Leaving for another day.
Currently we use the `Uint256` type to represent two proof of work
integers, namely target and difficulty (work).
It would be nice to not have a public integer type that is not fully
implemented (i.e., does not implement arithmetic etc as do integer types
in stdlib). Instead of implementing all the stdlib functions we can
instead add two new wrapper types, since these are not general purpose
integers they do not need to implement anything we do not need to use.
- Add a `pow` module.
- Put a modified version of `Uint256` to `pow`.
- Add two new wrapper types `Target` and `Difficulty`.
- Only implement methods that we use on each type.
Note this patch does not remove the original `Uint256`, that will be
done as a separate patch.
